Chapter 51, Problem 12TYU, SYNTHESIZE YOUR KNOWLEDGE Acorn woodpeckers (Melanerpes formicivorus) slash acorns in storage holes

Acorn woodpeckers (Melanerpes formicivorus) slash acorns in storage holes they drill in trees. When these woodpeckers breed the offspring from previous years often help with parental duties. Activities of these nonbreeding helpers include intubating eggs and defending stashed acorns. Propose some questions about the proximate and ultimate causation of these behaviors that a behavioral biologist could ask.

What are biofertilizers and mention the significance
PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen.     How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans?   Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
Other than oil and alcohol, are there other liquids you could compare to water (that are liquid at room temperature)? How is water unique compared to these other liquids? What follow-up experiment would you like to do, and how would you relate it to your life?
